Abstract: ABSTRACT:   A method and apparatus for agitating a material consisting of heavier and lighter phases flowing along a pipe, comprising injecting at least one steam of fluid into the pipe, characterised in that the fluid is injected into the pipe in such a way that it breaks up the concentration of the heavier phase and mixes this with neighbouring portions of the lighter phase and also establishes a twin-cell rotation effect which ensures that the resulting mixture is thoroughly inter-mingled with any remaining unmixed lighter phase.           The invention is particularly applicable to the oil industry.

Each terminal end of the arms is provided with an outwardly extending flange and a floss receiving groove, the groove at one terminal end being aligned with the groove at the other terminal end such that a length of the floss bridges the gap.  Each groove has a bottom defined by a rounded convex surface for frictionless engagement with the floss to permit the floss to freely slide thereon as the arms inwardly yield towards one another upon the application of tension  to the floss.  The flange of each arm includes a pair of opposed flange portions defining, as an extension of the groove, a guide opening therebetween for guiding the floss and maintaining same positioned on the bottom surface at each terminal end.  The dental floss holder of the invention further includes anchoring means for releasably securing the floss with the length thereof extending between the terminal ends of the arms being maintained under tension by the outward resilient force exerted by the arms.

Abstract: Abstract:   An eddy-current loop detector operates to sense the presence of an electrically conductive object by applying D.C. onto a conducting loop so that a permanent magnetic field is induced, which field partly penetrates into the object; ensuring the quick cessation of self inductive transient operation of the loop when the D.C. is switched off; and measuring the change in the part of the flux pass-ing through the measuring loop arising from eddy-currents induced in the conductive object, and evaluating such change while the relatively slowly decreasing flux is maintained.  By repeating these operations with the desired frequency, the eddy-current detector is well suited for continuous measuring of the position of the object.

Abstract: ABSTRACT          In the manufacturing of wood poles a number of sections are glued together along abutting side surfaces (7, 8) so that a tubular pole (19) with a central cavity is formed. The side surfaces (7, 8) which have been provided with glue are brought into intimate con-tact with each other so as to give a tube (19). Sealing covers (20, 21) of the like are placed at both ends of the tube so that these are sealed, whereafter air is pumped out from the central cavity (23) through one or both of the said covers so as to give a vacuum in the cavity in comparison with the external pressure, whereby the contact pressure between the abutting side surfaces increases. The vacuum is maintained until the glued joints (31) have been fixed.

Abstract: Abstract A microwave transmitter comprises a signal modulator for receiving an input signal that includes up to 75 video and audio channels and producing an amplitude modulated signal in the microwave frequency range corresponding thereto. An ampli-fier responsive to the microwave frequency signal produces an amplified output signal suitable for transmission to a remote location. The signal modulator and the amplifier have upper power limits which are sufficiently below their respective two-tone third order intermodulation intercept points that the carrier-to-triple-beat power ratios of each are respectively at least equal to first predetermined values. The gain of the amplifier is high enough that, notwithstanding the power limita-tion imposed on the microwave frequency signal by virtue of the upper power limit of the signal modulating means, the power of the amplified output signal is at least equal to a second pre-determined value. The sum of the gain and the noise figure of the transmitter measured in decibels has an upper limit deter-mined by the desired carrier-to-noise ratio and by thermal noise.

Abstract: SENSOR TIMER FOR LAMPS                    Donald E. Pezzolo James W. Pfeiffer Thomas E. Corder ABSTRACT    A sensor timer is provided for automatically turning on and off a lamp or alternatively for allowing the lamp to be manually turned on and off using the switch normally associated with the lamp.  The sensor timer automatically senses the arrival of nighttime despite seasonal variations in the actual time of nightfall and automatically turns on the lamp a first selected time period after nightfall.  The lamp is then automatically turned off a second selected time period after the lamp has been turned on or alterna-tively is turned on and off randomly during the second selected time period.  The sensor timer can also dim the lamp.  The sensor timer converts from automatic mode to manual mode in response to the turning on of the lamp through its manual switch thereby to allow the lamp to be controlled directly by the manually operated lamp switch.          To convert the sensor timer from manual mode to automatic mode the lamp switch is turned on, off and on in rapid succession.  The lamp then comes on for a brief period to inform the user that the sensor timer has been successfully converted to the automatic mode of operation.
